Philip Reeve is an English author and illustrator of children's books, primarily known for the 2001 book Mortal Engines and its sequels, the Mortal Engines Quartet (2001-2006). His 2007 novel, Here Lies Arthur, based on the legendary King Arthur, won the prestigious Carnegie Medal.

Born and raised in Brighton, Reeve worked in a bookshop for several years while also co-writing, producing, and directing a number of no-budget theatre projects. He then began illustrating and has since provided cartoons for around forty children's books, including the best-selling Horrible Histories, Murderous Maths, and Dead Famous series.

His other notable works include the Larklight trilogy and his science fiction novel Railhead, published by Oxford University Press in 2015. The book Pugs of the Frozen North, written with Sarah McIntyre, is another recent publication.
